grammaticality - I have a bodyguard in order to protect myself

I have a bodyguard in order to protect myself.

I was told that I cannot have a stative verb in the required condition:

I have a bodyguard

But I don't understand how "I need to study in order to pass the exam" is correct when "need" is stative.

I was also told that the subject has to do the infinitive, so the following is wrong:

in order to protect myself.

I was told the sentence should be written as:

I hired a bodyguard in order to stay protected.

Is this correct, or is there no problem with my original sentence?

My question is about in order.
